CPOL Innovation
CPOL is a new innovative intermediate used as the structural unit of the soft segment in high-performance polyurethanes, polyetheresters and other polymers to bring excellent flexibility, tensile properties Stretch and tear properties. CPOL is available in a variety of different molecular weight specifications, 1000, 2000 and 2900. While maintaining the excellent mechanical properties, functionality and hydrolytic stability of PolyTHF, the low-temperature mechanical properties and dynamic mechanical properties, especially the stretchability and tear resistance, of products based on CPOL series are better than those based on PolyTHF.

Core Advantages
Compared with many different polyols, CPOL has lower crystallinity, which results in a lower melting point of the soft segment, giving CPOL a very important advantage:

Better processability 高
The melting point of CPOL is significantly lower than that of PolyTHF. CPOL is liquid at room temperature, which makes its use more convenient. Because CPOL no longer needs to be heated and melted like PolyTHF before use, it can be used in areas such as spraying.

More prominent dynamics Mechanical properties
The structure of CPOL gives it significantly higher tensile properties. And the tearing performance of products based on CPOL is also particularly outstanding.
